DPF regen sounds strange at 88,000 miles. According to the service schedule, it should be *replaced* at 75,000 miles, and the Eolys fluid topped up. If you've got to 107K without the DPF being changed, then that's probably the issue.

Forgot to add, a regen is when it burns the soot off. This happens passively as the exhaust warms up, every 500 or so miles when the ECU decides to get the exhaust super-hot so as to burn the soot off, or can be forced through diag software. What you've been advised to do is passively regen it by getting the exhaust temps up on the motorway.
